Answer:
42.8°
Step-by-step explanation:
The sine rule states that for a triangle with lengths of a, b and c and the corresponding angles which are opposite the sides as A, B and C, then the following rule holds: 

Given that points A, B and C forms a triangle with angle A = 65°, distance from A-to-C = 90 m and the distance from B to C = 120 m. 
The distance from A to C is the side opposite to angle B. Hence let b =  distance from A to C = 90 m.
The distance from B to C is the side opposite to angle A. Hence let a =  distance from B to C = 120 m. 
Therefore using sine rule:
